Where do you get the 20 oz tank and how do you refill that? The whole meter set up with the reg for one of those is very pricey not to mention the tank itself.

you take the adaptor, and screw it into the big 20 pound propane tank, like you use on your grill. then you take the little blue propane tank, screw it onto the other side of the adaptor, and let the pressure equalise between the two.
that is what I got out of it. It mentions regulators or meters nowhere.

Are you sure its for one of those short fat grill ones? I don't think those are pressurized to 90psi. If it is thats good for me because my dad has 3 of those each from when he bought a new grill.
EDIT:Ewww! this instant macoroni and cheese tastes like crap, I don't even know why I'm eating it. I think I'm gonna go outside and shoot it out of my pneumatic. Maybe at somebody across the canal

Oh thats a great Idea schmanman. It would save you alot of money in the long run. I want to make a propane meter now so that i could use this and not have to buy a new tank every 200 shots.

well, you had that link to the harbor freight website in one of your posts, and I happened to stumble across this.

It's not worth the trouble for me. I run out of propane maybe once in, what, 3 months?

Propane is already cheap enough, 2.50 a bottle?

There are fittings like that at local hardware stores. It's best to make one with a shutoff valve in the middle.
Don't forget, you need to not just let pressure equalize, you need to turn the big tank upside down and let the liquid go into the small cylinder. Those big tanks are the same pressure as the small ones and they are liquid.
